There are 3 types of muscles: cardiac, smooth and skeletal
Cardiac muscle make up the heart walls and is responsible for controlling the heart
smooth muscles are found in the intestines and blood vessels, are involuntary
Skeletal muscles: muscles attached to the bone and allow you to move and perform, are voluntary
Where are smooth muscles found?
In the intestines and blood vessels
where are cardiac muscles found?
In the heart
Which muscles are involuntary
Cardiac and smooth muscles
what muscles are voluntary
Skeletal
Muscles creating the movemtn is known as Agonist
Muscles that relaxes are known as the Antagonist
Muscles that contract to hold the surrounding bones still are known as stabilizers
Movement is when the muscles contract or Shorten. Muscles work in pairs so when 1 muscle contracts the other relaxes. This is known as Reciprocal Inhibition.
Superior is towards/closer to the head
Inferior is further/ away from the head
Anterior is towards the front of the body
Posterior is towards the back of the body
Medial is closer to the midline of the body
Lateral is further from the midline of the body
Proximal is closer to the attachment point
Distal is further from the attachment point

what are the 4 roles of the skeletal system?
body movement, frameworkandprotection, mineral storage, productionofred blood cells.
what does framework and protection do
assistustostanduprightandto protect vital organs
where is the production of red blood cells
in bone marrow inside of long bones
how many bones are in the vertebral columm
33, 24 unfusedand9 fused
Cervical has 7 unfused bonesand is responsible for supporting theneck
Thoracic has 12 unfused bones allowing connection between spineandribcage as well as protects heartandlungs
Lumbar has 5unfused bones, largest vertebraeto hold the body's weight
